§ 04 / About

A short biography,
About me.

There is, strictly speaking, only one person here. Everything else is borrowed light.

I am a full-stack developer working under the name seven. Currently a sophomore studying Computer Science at Asia University, and serving as Co-Founder & CTO of Deebug Co., Ltd. I am passionate about development and love the process of turning ideas into reality.

As a full-stack developer, I focus on building products that are both beautiful and functional — from frontend interface design to backend systems, all the way to mobile app development and distribution. My stack spans TypeScript, Python, Dart, Java, and Swift, with frameworks including Next.js, Flutter and SwiftUI.

At Deebug, I led the cross-platform technical integration for VALKI — using Flutter for the mobile app and Java for the backend service — growing the product to over 140,000 active users. I also independently develop and maintain several open-source tools and personal projects, including the TronClass API integration library, the TimeNest context-aware time management app, and the OLLM AI chat platform.

I read more than I write, and I write more than I publish. I believe that good software should be invisible to the user, and that focused attention is the most undervalued skill in this industry.

§ 04.1 / Principles
How I try to work.
Reminders to myself, repeated often enough that I sometimes manage to follow them.
i.
Edit, then ship.

Half the time spent on a thing is taking other things off it. I now write a "what's not in this release" list before I write the release notes.

ii.
Parallel, but prioritised.

Running multiple projects at once is the norm, not the exception. The key isn't doing one thing — it's always knowing which thing matters most right now.

iii.
Write everything down.

Every decision becomes a document. Every document becomes a draft. Every note is a memo to a future self or someone I haven't met yet.

iv.
Users first.

The ultimate judge of software quality is the user, not the engineer. Before writing code, understand whose problem you're solving.
